Is it at all possible to cram an fj60 a/c unit, blower, compressor, dryer, etc into a 55? I have been looking at some donor 60's and it looks like they would fit with some minor fabbing.

Any other easier options to think about.

I live in the depths of hell, AC is a must down here!!!!!

Thats crazy, i was looking at a donor 60 today and wondering the exact same thing !
 
I bet that it could work, the only problem or hiccup I could see is getting the inboard parts to fit under the dash and cutting the control free from the sixty dash and putting them in the 55's dash some where. Probably just in place of the old one.....
 
I have put AC from a 60 in a non AC HJ60 before.. I have been thinking a lot aobut this, I will be attempting to use 80 series stuff but if not 60 will be my other option! 60s also use nice standard fittings while 80s use all sorts of weird stuff.. The only issue I think will be the wiring, if you want to keep it functioning OEM... Basically, AC works by turning on the compressor only. In FJ60s, they use a circuit board with a few safety parameters and control / determine an idle-up function.. The AC board is right on the passenger side of the AC unit, toyota refers to it as an "amplifier." The safety functions I think are a temp function (if it gets too cold) and it has a freezing / moisture sensor so it will also shut it self off if it starts getting some humidity / freezing / icing). Nothing wrong with this, but it also has a sensor off the coil, then it has another idel up function on the FJ60 era carb that increases idel when AC is on...

So your options are:

1) use all FJ60 coil / carb / electronics. this is a PITa especially for desmogged / earlier engines.

2) Run a BJ60 era amlifier that uses the safety items but there is no idel up function. this is good in terms of ease of wiring but you might experience some running problems because it cannot idel up. maybe use a hand throttle ot increase idle up? Also this part appears to be discontinued. I ordered it sucessfully a couple of years ago. Also one of the japan listers might be able to get it and ship it..

3) Run a straight wire to the compressor and risk the icing factors...
 
The condenser in a 60 is huge, like most modern ones. The space in a 55 is tiny. You would have to mount the condenser in front of the radiator and move the rad back, or use a different condensor. I'm looking at a Honda Civic one. It's narrow and tall and looks like it'll fit. I just hope it has the correct fittings.

I thought Vintage Air made a good kit that worked well? I have a complete setup from a '78... saving for??? I was eventually going to go with the Vintage Air kit figuring it would be more efficient? Does yours work really well Cruiser Guy?
 
When I built up the A/C for my 40 I used a 85 ford ranger condensor because its super thin , and a 86 ranger compressor (has the clamp on hose ends so no special hoses need to be made) Used a early 80,s pontiac reciever drier(again clamp on ends for it and a sight glass built in). Used a under the das unit for out of a old chevrolet.(any make will do) the compressor is wired through a basic old style t-stat that has the gas tube stuck in between the evaporator coil fins (this cycles the compressor) . This is a old r12 setup I run freeze12 in ( runs 10% less so leave a few bubbles in the sight glass )and I put out 42 deg at the vent. I have the same parts going in my piggy when I get to that stage. No idle up solenoid and it only drop 100 rpm when on. I played around with diffrent condensors until I got the head pressure I liked. I also added a inline high pressure cut out so when you got on it the head pressure wouldnt go out of sight. I have about $100 bucks in the whole thing. Only thing I bought new was the drier and some hose. The freon I had on my work truck.

I'll let you have a look when I stop by for the hood later this year.

It's not as nicely laid out as a new vehicle so you tend to be colder on the part of you near the center of the truck and warmer on the outside because all the air is vented through the center vents but it sure beats no A/C!!

The '60 of course can vent the A/C out the side vents and the center so it's more comfy that way.

Give Mike Harness a call at Atlanta Custom Cruisers as they did this exact mod to a customer's rig:
